i aia Application filed. June 26,

To all whom it may concern Be it known that I, Marnncn Mirna,manufacturer, a subject er the King of Belgium, and resident of Liege,in the Kingdom of Belgium, have invented certain new and usefulImprovements in or Relating to the Production or Bottles or OtherVessels and Apparatus Therefor; and I do hereby declare the following tobe a full, clear, and exact description of the invention such as willenable others skilled in the art to which it appertains to make and usethe same reference being had to the accompanying drawings, and toletters or figures reference marked therein, which form a part of thisspecification.

The present invention relates to a chine for manufacturing bottles orother vessels by blowing, this machine being essentially differentiated"from known machines of the kind by the fact that the bottom of themould rises inside the body of the mould in such a way as to raise theupper level of the blank to the upp 1' level or the bottle or othervessel to be obtained. When the blank occupies this position a toolcarried by a bracket is inserted into the blank so as to form the holefor the upper part of the neck. This tool is Withdrawn and then swungaway from the mould by rotating the bracket that carries it, after whicha compressed-air supply device terminating in a suitable nozzle andcarried by another bracket, is brought over the mould and enables theblowing to be eiiected. ll. he apparatus is completed by the provisionof means enabling the bottle or other vessel to be rotated inside themould.

This machine, which is or particularly simple and strong construction,enables a large output of a product of good quality to be obtained. Theabsence oi any joint in the body of the mould permits bottles or othervessels to be formed without ribs and consequently of great strength.

The drawings accompanying this specification illustrate by way ofexample one constructional form of the invention.

In these drawings:

figure 2 is a cross section on the line in Fig. 1.

Figure 3 shows, on a larger scale, the operation of forming the upperpart of the neck in the case or a bottle.

Figure shows. on the same scale as Figure 3 the operation of blowing acarboy.

Figure 5 shows, on a different scale the nozzle of the blowing pipe,when it is not applied to the mould. I

The frame 1 of the machine, carried by wheels 2. is provided with twoshafts 3 and i serving to support the brackets 5 and 6. The radii of thearcs traversed by the brackets are such that each of the devicesdescribed above may be brought over the axis of the mould '7.

In line with the axis oi this mould 7 is arranged a vertical rod 8forming an extension of a small piston 9. which is displaceable in acylinder 10 filled with oil and communicating with a cylinder 12 inwhich there moves a large piston 13 which can be worked by hand by meansof the lever it.

The mould 7 consists of three parts, viz- (1) the bottom 7 carried bythe rod 8;

(2) the body 7 consisting of a hollow vertical cylinder;

(5) and a displaceable top or neck part 7" hollowed internally andshaped according to the external shape of the neck of the bottle.

Tl e tool that serves to form the necks consists of a punch 15, which isworked by lever 16 and which a balance weight 17 tends to raise. On tothe rod 18, to which is fixed this punch 15. is lined a cross bar 19traversed by two rods 20 carrying a plate "21 pierced with a hole 22.Spriiiigs tend to move the plate 21' away from the cross bar 19. Thispunch 15 is kept hot by the lame of a lamp 36.

The compressed-air supply pipe is supported by the bracket 6 pivoted onthe shaft 1. It is displaceaole vertically and can be lowered by meansof a lever 24 provided with a balance weight 25 tending to raise it. Itterminates at the bottom in a nozzle constituted as follows, (seeFigures a and 5): The terminal nozzle 26 is fired to a tube 27 which ismovable in a socket 28 lined to the extremity of the tube 23. This pipe27 is provided with two valves 29 and LO the apices of which aredirected one to wards the other. It is closed at the top the top of theneck.

but is pierced with holes between the two valves. -W hen the terminalnozzle 26 is not pressed against a support, that isto say, when it ishanging freely, (see Figure the upper valve 29 rests against its seatand keeps the compressed-air passage closed. W hen on the contrary thenozzle 26 is raised in consequence of it coming into contact with an.immovable object, such as a mould, it is displaced with respect to thesocket 28 in such a way that the valve 29 leaves its seat and the valve30 is pressed on to its own seat in such a way as to close the bottom'ofthe passage 1 in which the tube 27 moves. The compressed air passingunder the valve 29 then traverses this passage 31, enters the tube 27through the holes therein, flows through said tube ,and finally reachesthe terminal nozzle 26.

The apparatus operates in the following manner:

The mold being mounted as shown in F 1gures l, 3 and 4, the blank isinserted therein, and then, by acting on the lever l t the bottom 7 israised until the blank is flush with The lever 16 is then operated so asto apply the plate 21 against the upper face of the part of the mould.

y continuing to operate the lever 16 the punch. is made to penetratethrough the hole 22 in the plate 21 into the mouth of the bottle. Duringthis movement the springs are compressed and press the plate 21energetically against the part 7 of the mould so as to form a tightjoint. "When the mouth is formed in this way, the lever 16 is let go andunder the action of the balance weight 17 it rises, thereby raising thepunch 15. The bracket 5 is then moved away and the bracket 6 is rotatedin such a way as to bring the nozzle 26 over the axis of the moulc. Byoperating the lever 24 the nozzle 26 carried by the pipe 23- ispressed-against the part 7 of the mould, the continued descent of thepipe 23bringing about the supply of air through. the said nozzle asexplained above. This air, by entering' the mouth, effects the blowingof the bottle. During the blowing the bottom 7 of the mould is lowered.

If it is desired to rotate the article that is being blown in the mould,the bottom 7 of'the mould is provided with projections entering a littleway into the bottom of the bottle, and this bottom 7 is rotated throughthe medium of a pinion 33 electric motor the machine.

This pinion 33 has a key-and-groove connection with shaft 8, so that notonly is the pinion enabled to rotate said shaft, but said pinion andshaft are rendered capable of relative axial displacement, such displacement allowing the bottom 7 to rise.

It is to be observed that the part 7 of the mould can be cooled by thecirculation of air through the annular space 35. The cooling so producedtempers the glass,

What I claim is:

1. A machine for the mechanical manufacture of bottles or other vessels,comprising a frame, a mould fixed on said frame, means for raising theblank inside the mould until it is flush with the upper part of theneck, a pair of movable brackets mounted on the aforesaid frame, a toolsupported by one bracket for making a hole in the blank, and meanssupported by the other bracket for supplying compressed air in the holeof the blank, said brackets being arranged to permit said tool and saidair-supplying means .to be brought one after the other over the mould.

2. A machine for the mechanical manufacture of bottles or other vessels,comprising a frame, a mould fixed on said frame, means for raising theblank inside the mould until it flush with. the upper part of the neck,a pair of movable brackets mounted on the aforesaid frame, a toolsupported by one bracket for making a hole in the blank, a compressedair supply pipe supported by the other bracket and terminating in asocket provided with a passage, a tube terminating in a nozzle andmoving in said passage, and valves arranged on said tube for closingsaid passage when the nozzle hangs freely and for supplying the pipewith air when said tube is raised within the socket, said brackets beingarranged to permit said tool and said air supplying pipe and itsassociated tube to be brought one after the other over the mould.

In testimony whereof I affix my signature in presence of two witnesses.
